I can genuinely offer 2.75%... If my brother does not take up the offer soon. Basically you keep access to your cash (you fill in a form to link your bank to my mortgage to offset my 4% mort) and I'll give you a payment to the degree of 2.75%, as often as you want. Monthly works well. I make 1.25%
Catches;
I see how much you have in the account
Over £30k and I'll have to think about the capacity I have.
Under £10k and I'll have to think about using the offer with someone with more cash spare.
You need to open a YBS account and fill in a form
Equally it's an extra admin task as/when you want to stop using me because I have to delink your account and setup someone afresh. For this reason, whilst I can offer for a few years, I wouldn't want someone to start saving through me for only a matter of months.
If you want info, let me know. I can link 2 accounts, do this with one mate £50k and am waiting on my bro re the other (but it's likely he may not have the £££)
